After age 40, GFR decreases progressively with age, by 0.4–1.2 mL/min per year. [citation needed] Estimated GFR (eGFR) is now recommended by clinical practice guidelines and regulatory agencies for routine evaluation of GFR whereas measured GFR (mGFR) is recommended as a confirmatory test when more accurate assessment is required.

A major measure of kidney function is the glomerular filtration rate (GFR). The glomerular filtration rate is the flow rate of filtered fluid through the kidney. The creatinine clearance rate (C Cr or CrCl) is the volume of blood plasma that is cleared of creatinine per unit time and is a useful measure for approximating the GFR. Creatinine ...
A glomerular filtration rate (GFR) ≥ 60 mL/min/1.73 m 2 is considered normal without chronic kidney disease if there is no kidney damage present. Kidney damage is defined signs of damage seen in blood, urine, or imaging studies which includes lab albumin/creatinine ratio (ACR) ≥ 30. [ 59 ]
Levey is known for developing the most widely used equations to estimate GFR (renal function) globally.He pioneered work with the MDRD Study Equation, [1] led the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI), which pooled measured kidney function CKD data from studies all over the world to develop equations to estimate kidney function from serum creatinine, cystatin C, and ...
This is the numerator in the equation. The denominator is the total amount of sodium filtered by the kidneys. This is calculated by multiplying the plasma sodium concentration by the glomerular filtration rate (GFR) calculated using creatinine filtration. The flow rates then cancel out, simplifying to the standard equation: [1]

Rapidly progressive glomerulonephritis - This is a syndrome of the kidney that is characterized by rapid loss of kidney function (usually >50% decline in glomerular filtration rate (GFR) within 3 months) [23] with glomerular crescent formation frequently seen on kidney biopsy.
